To all whom it may concern.

Be it known that I, ROBERT BAGLEY, a citizen of the United States,residing at Leavenworth, in the county of Chelan, State of Washington,have invented certain new and useful Improvements in Emergency-Derailers, of which the following is a speci fication.

This invention relates to devices for derailing cars and has specialreference to devices for carrying the de-railing frog on the engine, ortender, when it is not in use and for applying it to the rail when thetrain is running away.

The objects of the invention are to provide means whereby the engineerof a runaway train may simultaneously disconnect the engine from thetrain and de-rail the train, thus saving the engine from disaster andmaking it unnecessary for the engin crew to jump from the engine.

Further objects are to provide such a mechanism as will be simple andcheap to make, easy to operate and positive in action.

I attain these and other objects by the devices, mechanisms andarrangements illustrated' in the accompanying drawings, in which- Figure1 is a side elevation of a portion of a geared locomotive, showing myderailing apparatus mounted thereon, ready for use; Fig. 2 is a similarview, showing the parts in the positions occupied thereby when thede-railing frog has been thrown rearward onto the rail and the firstwheel of the train has begun to climb thereon; Fig. 3 is a cross-sectionof my apparatus on the line 0ta in Fig. 4;; Fig. 4 is a longitudinalsection on the line Z b in Fig. 3, showing the frog being placed inposition on the carrier; Fig. 5 is a side elevation of the frog inposition on the carrier; Fig. 6 is a plan thereof; Fig. 7 is aperspective view, from below, showing the carrier; Fig. 8 is a similarview of the frog; and Fig. 9 is a side elevation showing a variation ofthe apparatus, in which air pressure is used to project the frog insteadof a spring.

Similar numerals of reference refer to similar parts throughout theseveral views. This invention is particularly adapted for use in loggingor other freight trains and is intended to lessen the cost of a wreckdue to a train running away by reducing the damage done. When theengineer loses the control of a train and it runs away, the only thingthe train crew can do is to jump from the train, under considerable riskto life and limb, and the-train continuesits wild course until it isthrown from the track by some switch, curve, or irregularity or meetssome other obstruction. The damage of such a wreck is largely in thedestruction of the engine. In order to reduce this cost I mount ade-railing frog on the rear of the engine and, when the engineeractuates its releasing mechanism, it is projected rearward at about thesame speed as the forward speed of the train, with the result that itactually will drop vertically on to the track and will reach the trackat practically the same instant that the wheel of the first car reachesthe frog. This de-railing frog may then slide until it engages a tie andthen the said wheel climbs on its back and is thrown laterally by thede-railing flange thereon, thus causing the car to leave the rails. Eachwheel as it reaches the said frog is thus ole-railed until theresistance of the de-railed cars to forward motion has absorbed theenergy of the runaway train. Meantime the engine may conveniently havebeen detached from the train at the same time that the frog wasprojected from the engine.

' Referring now to the drawings :the engine 1 is provided with a rearsill 2 to the under side of which a pair of hangers 3 are attached.These hangers 8 extend vertically downward fromthe sill 2 and are sideby side but spaced slightly apart. A strap 4: is secured to the twohangers 8 near their lower ends, said strap extending a short distancetoward the front of the engine. Two short carrier bars 5 are secured tothe inner sides of said hangers 3 near the lower ends, said bars 5 beingsubstantially l.- shaped and having V-shaped tracks 6 formed thereon,whereon the hereinafter described wheels of the de-railing frog aresupported. A pair'of angle-irons 7 are also secured to the said hangers3 above the bars 5 and parallel therewith, said angle-irons beingadapted to hold the said de-railing frog down on the tracks 6. A strongspring 8 is secured to the center of the strap 4 and extends therefromrearward and is adapted to proj ect the said de-railing frog along thetracks, rearward, whenthe frog is released.

The de-railing frog 9 is constructed in substantially the same form asis usual with such a device, having a pair of legs 10, one lying on eachside of the rail when in its operative position, and having claws 11adapted to engage and hold a tie and a central car-lifting part 12 witha derailing flange 13 thereon. This device also has four grooved wheels14 mounted on its lower flanges, said wheels being positioned so astoride on the tracks 6 of the carrier bars 5, and a pair of flanges 15on the upper side of each side, said flanges 15 being adapted to engageunder the angle-irons 7 to hold the wheels 14 down on the tracks 6. Apair of notches 16 are formed in the lower edges of two of the flangesof the frog, said notches being positioned and adapted to receive thehooked ends of the two retaining dogs 17. These dogs 17 are mounted on arod 18 which is supported by and passes through the lower ends of thehangers 3 and which is provided with a lever 19 by which the said dogs17 are held in the notches 16 and are withdrawn therefrom to release thesaid frog. The lever 19 is connected by a rod 20 to the hand controllever 21 mounted on the side of the engine 1 in any convenient position.The lever 21 is provided with the usual locking means whereby it is heldfrom accidental movement. The coupling pin 22 may be operativelyconnected to the lever 21 by a rod 23 or, as shown in dotted lines, maybe connected to a separate operating lever 24.

As before mentioned, the spring 8 is very stifl and I have thereforedevised the following means for compressing it and for bringing the froginto position in the carrier frame. The strap 4L has a centralscrewthreaded hole 25 therein, wherein the screwthreaded rod 26 may bescrewed. This rod 26 has a crank-handle 27 formed thereon. The inner endof the rod 26 has a shank 28 adapted to pass freely through the hole 29in the center of the frog 9. A collar 30 is connected by'a pin to theend of the shank 28 and engages the inner side of the flange of thefrog. Thus by turning the crankhandle 27 the rod 26 is screwed out(toward the front of the engine) and the frog 9 is drawn forward and thespring 8 is compressed. As soon as the frog has been thus drawn to itsposition the notches 16 are engaged by the dogs17 and thus the frog isheld from movement under the action of the spring 8, then the rod 26 maybe reversed and the collar 30 removed therefrom, and then the rod may beentirely removed.

In Fig. 9 I have shown a variation in the above-described apparatusadapted for engines which have compressed air thereon for use in airbrakes or other purposes, in which air pressure is substituted for thespring 8. The cylinder 31 has a piston therein and a piston rod 33projecting rearward therefrom to engage the frog 9. The rear end of Ithe cylinder is sufficiently open to allow the free passage of airtherefrom. IV hen air is admitted to the front end of the cylinderthrough the pipe 3%, and when the dogs 17 have been released as abovedescribed, the piston is forced rearward and the frog is projected asabove described.

Having described my invention, what I claim is 1. In an emergencyde-railer, the combination with an engine traveling on a track; of acarrier frame mounted on the rear of said engine; a de-railing frogmounted in said carrier frame; and means mounted on said carrier frameand engaging said frog whereby said frog may be projected rearward toengage the rail in front of the wheel of the following car.
